whipple S/C question

[GI Joe]

What pulley size is considered max for stock motor. Which is 500 hp?

it should be similar to a KB. I made 520 on a 10psi pulley on race gas with high timing so i figure maybe 12psi on a conservative timing tune for 500rwhp

Haven't been dyno'd yet, but i'm running a 11.8 on 20's with a crappy 2.01 60 foot but a nice 119 trap speed. If I could hook up, i'd be running an 11.4 on the 20's. I'm using 93 octane gas, i'm not into the racing fuel.
